The catchsquare WP Social Widget plugin for WordPress versions up to 2.2.5 contains a stored cross-site scripting (CWE-79) vulnerability due to improper input neutralization during web page generation. This flaw allows an attacker with low privileges to inject malicious scripts that could be executed in the context of other users, potentially impacting confidentiality, integrity, and availability to a limited extent. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with a scope change and low impact on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to information disclosure, session hijacking, or other limited impacts on the affected system. The impact is rated as medium severity, reflecting limited but non-negligible risk. There are no reports of active exploitation in the wild.
